My husband and I are retired.I volunteer at the local library each Thursday that we are at home. We have a RV and try to use it as much as possible. All our trips are not long or for long distance. We live in North East TN so have the mountains to enjoy. I am also a gardener. I have swaped books at the campgrounds for years(leave a book-take a book) but this was the first time I had seen a BookCrossing book. I will continue to take and leave a book. I usually use the library when I am at home so I do not have a large selection of books at home.
